Viatris Methylphenidate is not indicated for the treatment of ADHD in children under 6 years.

How it works

Viatris Methylphenidate improves the activity of certain parts of the brain that have low activity. The medication may help improve attention (level of attention), concentration, and reduce impulsive behavior.

The medication is administered as part of a comprehensive treatment program, which usually includes therapy:

• psychological,
• educational, and
• social.

Only doctors with experience in behavioral problems in children or adolescents or adults prescribe it.If you are an adult and have not received treatment before, the specialist will perform tests to confirm that you have had ADHD since childhood.Although ADHD has no cure, it can be controlled using comprehensive treatment programs.

About ADHD

Children and adolescents with ADHD have:

• Difficulty staying still.
• Difficulty concentrating.

It is not their fault that they cannot do these things.

Many children and adolescents struggle to do them. However, ADHD can present problems in daily life. Children and adolescents with ADHD may have difficulty learning and doing homework. They have difficulty behaving well at home, in school, and in other places.

Adults with ADHD often have difficulty concentrating. They often feel restless, impatient, and distracted. They may have difficulty organizing their personal and work life.

Not all patients with ADHD need medication treatment.

ADHD does not affect intelligence.

Checks your doctor will make before you or your child start taking methyphenidate

These checks are to decide if methyphenidate is the right medication for you or your child. Your doctor will talk to you about:

• The medications you or your child are taking.
• If you have a family history of sudden and unexplained death.
• Other medical problems (such as heart problems) you, your child, or your family may have.
• How you are feeling, if you have mood swings, have strange thoughts, or have had feelings of this type in the past.
• If there have been cases of tics in your family (repetitive movements that are difficult to control in some parts of the body or repetition of sounds and words).
• Any behavioral or mental health problems you, your child, or other family members have had. Your doctor will explain specifically if you or your child are at risk of developing mood swings (from being manic to being depressed, known as "bipolar disorder"). Your doctor will check your mental health history and if any family member has a history of suicide, bipolar disorder, or depression.

It is essential to provide all the information you can. This will help your doctor decide if methyphenidate is the right medication for you or your child. It is possible that your doctor will decide that you or your child need other medical tests before starting to take this medication.For adults starting to take methyphenidate, your doctor may refer you to a cardiologist.

During treatment, children and adolescents may experience, unexpectedly, prolonged erections. Erections can be painful and occur at any time. It is essential to contact your doctor immediately if the erection lasts more than 2 hours, especially if it is painful.

Other medications and Methyphenidate Viatris

Inform your doctor or pharmacist if you or your child are taking, have taken recently, or may need to take any other medication.

Do not take methyphenidate if you or your child:

• Are taking a medication called "monoamine oxidase inhibitor" (MAOI), which is used for depression, or have taken an MAOI in the last 14 days. The use of an MAOI with methyphenidate may cause a sudden increase in blood pressure (see "Do not take Methyphenidate Viatris").

Inform your doctor or pharmacist if you are taking any of the following medications for depression or anxiety:

• Tricyclic antidepressant.
• Selective serotonin reuptake inhibitor (SSRI).
• Serotonin and norepinephrine reuptake inhibitor (SNRI).

Taking methyphenidate with these types of medications may produce a potentially fatal increase in "serotonin" in the brain (serotonin syndrome), which can cause confusion or restlessness, sweating, chills, muscle spasms, or rapid heartbeats. If you experience these adverse effects, seek medical attention immediately.

If you or your child are taking other medications, methyphenidate may affect the efficacy of these medications or cause adverse effects. If you or your child are taking any of the following medications, consult your doctor or pharmacist before taking methyphenidate:

• Other medications for depression, medications for severe mental health problems.
• Medications for Parkinson's disease (such as levodopa).
• Medications for epilepsy.
• Medications used to lower or raise blood pressure.

• Medications that thin the blood to prevent clotting.

If you have any doubts about whether any of the medications you or your child are taking are included in the above list, consult your doctor or pharmacist for advice before taking methyphenidate.

Inform your doctor or pharmacist if you or your child are using or have used recently any other medications, even those purchased without a prescription.
